similar structure, combining great wear resisting qualities with unusual hardness and strength, and one that will not. crack under ordinary strain, all as, will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, v

Figure 1 shows a section through a floor with my said invention, and I v Figure 2 is a plan view showing the various layers at different points in the floor.

The I-beams A and base structure B are or may be of any reinforced concrete construction and require no special description. On the top of base B, a layer 10 is placed consisting of a mixture of one part of Cemite cement and three parts of Joplin chat or Zinc refuse, or crushed flint rock-of a size that will pass through a or inch mesh screen. To this I add 2 lbs. of satinette asbestos (short fiber) to each sack of Cemite cement used with the mixture. This is spread over the concrete base in a layer 2% to 3 inches thick. On top of this I apply a web 11 of flexible veneer strips approximately one inch wide and of an inch thick woven into an open basket weave and applied on the base while wet, and substantially imbedded therein. On top of this I spread a layer 12 comprising an aggregate of marble, granite or flint rock chips reduced to 4 inch mesh of a variety of colors and evenly distributed over the Cemite cement and imbedded therein. I then spread a surface layer 13 formed of a mixture of Cemite cement and asbestos (short fiber) in the pro portion of 3 lbs. of asbestos to each bag of cement which is poured over the marble or stone chips to entirely cover them. The massis then allowed to cure for approximately three days when a rotary smoothing machine equipped with carborundum blocks is pushed over the entire surface until the surfaces of the aggregates are exposed and the surface is perfectly smooth. By this means a floor is provided of a mottled ap pearance, quite attractive in character, and one that is tough and capable of resisting unusual wear and strain. 7

At points above the posts or supporting columns a section 14 of wire mesh or similar reticulated material is placed to reinforce the floorat such points.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

I l. A floor, etc, for fire proof buildings, comprising a reinforced fire proof base, a layer of a mixture composed of cement and crushed rock on said base, a web formed of strips of veneering on top of said mixture and another layer of rushed stone on top of said web, and then a layer of cement mixed with fiber covering said last material, substantially as set forth.

2. A fire proof floor construction com prising a supporting base, a floor base over said supporting base composed of a mix ture of cement, crushed rock and fiber, a flexible binder imbedded in the upper surface of said floor base composed of flexible strips, a layer composed of a mixture of crushed mineral substance over said flexible strips, and a top layer composed of a mixture of cement and fiber, substantially as set forth. 4

3. A floor, etc. for fire proof buildings comprising a base consisting of a mixture of cement and crushed mineral, a flexible web on top of said base, a layer of crushed mineral on top of said web. and a surface layer consisting of cement mixed with fiber with portions of the crushed mineral exposed,

substantially as set forth.

{.t. A floor etc. for fireproof buildings comprising a base mounted on supporting columns, a' layer of Cemite cement and crushed mineral on said base, a flexible web on said layer, a section of re-enforcing materialembodied in the base above the supporting columns, a layer of crushed mineral on said web, and a surface layer composed of Cemite cement and fibre, substantially as set forth.

5. A floor, etc, for fire proof buildings, comprising a reinforced fire proof base, a layer ofa mixture composed of cement and zinc refuse on said base, a Web formed of my hand and seal at Indianapolis, Indiana, strips of veneering on top of said mixture this 12th day of October, A. D. nineteen and another layer of crushed stone on top of hundred and twenty. said Web, and then a layer of cement mixed EDVARD F. KELLIE.
